DETAILED DESCRIPTION

[0022] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] This embodiment provides a technical solution: a chest strap for fixing after cardiothoracic surgery, such as Figure 1 As shown, it includes a gauze sheet 1, two fixing parts and two disassembly and assembly mechanisms 3. The gauze sheet 1 is used to cover the wound of the patient, and its size can be set according to the needs of the patient;

[0025] The two fixing parts are respectively bonded and fixed to both sides of the patient's upper torso, and the fixing parts include a fixing cloth 21, on which adhesive tape 22 is provided. The number of adhesive tapes 22 is set according to needs, and the adhesive tape 22 is used to be bonded and fixed to the patient's skin, thereby avoiding the bandage from being wrapped around the patient's back. After use, it can be torn off to complete the disassembly; a plurality of first fixing strips 23 are fixed on the fixing cloth 21, and the ends of the first fixing strips 23 are connected and fixed to the disassembly mechanism 3. The vertical dimension of the disassembly mechanism 3 is smaller than the vertical dimension of the entire fixing part (with reference to when it is worn on the patient), thereby preventing the disassembly mechanism 3 from causing inconvenience to the patient's movements.

[0026] The two disassembly and assembly mechanisms 3 are respectively installed on the two fixing parts, and the two disassembly and assembly mechanisms 3 are respectively detachably connected to the two sides of the gauze piece 1, so that the gauze piece 1 can be removed or installed from the patient's body and the dressing can be changed for the patient without the patient getting up, thereby avoiding discomfort to the patient and bringing convenience to medical staff.

[0027] Embodiment 2

[0028] This embodiment is further optimized on the basis of the first embodiment, and the same parts as the above technical solution will not be repeated here. Figure 1-2 As shown, in order to better realize the utility model, the following setting is particularly adopted: the disassembly and assembly mechanism 3 in this embodiment includes a first hard thin plate 31 and a hook block 13, and the first fixing strip 23 is connected and fixed to the first hard thin plate 31;

[0029] The hook block 13 is connected to the gauze piece 1, and the specific connection method is: the side of the gauze piece 1 is fixed with a second hard thin plate 12 through multiple second fixing strips 11, and the vertical dimension of the second hard thin plate 12 is smaller than the vertical dimension of the gauze piece 1 to prevent the second hard thin plate 12 from causing inconvenience to the patient's movement, and the hook block 13 is installed on the second hard thin plate 12. In order to improve the patient's comfort, the bottom of the first hard thin plate 31 and the second hard thin plate 12 are fixed with soft blocks 32, and the soft blocks 32 can be sponge or rubber.

[0030] A rope 33 is fixed on the first hard thin plate 31, one end of the rope 33 is fixedly connected to the first hard thin plate 31, and a tensioning member is provided on the first hard thin plate 31. The rope 33 passes around the hook block 13 and is connected to the tensioning member. The rope 33 presents a V-shaped structure as a whole. The rope 33 is contracted by the tensioning member to tighten and fix the gauze piece 1, and then the gauze piece 1 is tightened to fit the patient's torso. Conversely, when the gauze piece 1 needs to be removed, the rope 33 is loosened by the tensioning member, and the rope 33 is removed from the hook block 13, so that the gauze piece 1 can be lifted up and the patient's wound can be changed.

[0031] Embodiment 3

[0032] This embodiment is further optimized on the basis of the second embodiment, and the same parts as the above technical solution will not be repeated here. Figure 2 As shown, in order to better realize the utility model, the following setting method is particularly adopted: in this embodiment, the tensioning member includes a winding drum 35 rotatably mounted on the first hard thin plate 31 through a rotating shaft 34, and the end of the rope 33 is wound and fixed in the winding drum 35. When the winding drum 35 rotates, the rope 33 can be wound around the winding drum 35 or loosened from the winding drum 35; the end of the rotating shaft 34 is provided with an anti-slip groove 36, and the setting of the anti-slip groove 36 can increase the friction force, which is convenient for the user to rotate the rotating shaft 34, and a limiting structure for limiting the self-rotation of the rotating shaft 34 is provided between the first hard thin plate 31 and the rotating shaft 34.

[0033] Furthermore, the limiting structure includes a mounting block 373 fixed to the first hard thin plate 31 and a locking plate 371 fixed to the rotating shaft 34. A sliding hole is provided on the side of the mounting block 373 close to the locking plate 371. A sliding rod 375 is slidably installed in the sliding hole. A spring 374 is installed in the sliding hole to drive the sliding rod 375 to move outward. A push block 376 is fixed to the sliding rod 375. Specifically, a long waist hole connected to the sliding hole is provided on the mounting block 373. The push block 376 penetrates the long waist hole and is fixedly connected to the sliding rod 375. The sliding rod 375 can be pushed into the sliding hole by the push block 376.

[0034] The outer circumferential surface of the locking plate 371 is provided with a plurality of annularly distributed grooves 372. The end of the slide rod 375 is provided with a limiting block 377 that matches the groove 372. Under the action of the spring 374, the end of the limiting block 377 enters into the corresponding groove 372, thereby limiting the rotating shaft 34 from rotating automatically.

[0035] A first inclined surface is provided on one side of the groove 372, and the first inclined surface is on the opposite side of the rotation direction of tightening the rope 33, and the limiting block 377 has a second inclined surface adapted to the first inclined surface;

[0036] Therefore, when the rotating shaft 34 is rotated, due to the cooperation between the first inclined surface and the second inclined surface, the limiting block 377 will be pushed out of the groove 372 and the spring 374 will be compressed. When it moves to the next groove 372, the limiting block 377 will be moved into the next groove 372 due to the force of the spring 374. Since the other side of the groove 372 is not provided with an inclined surface, the winding drum 35 can be prevented from reversing by itself. When the rope 33 is to be loosened, the pushing block 376 is used to push the sliding rod 375 into the sliding hole, so that the limiting block 377 is disengaged from the groove 372, and the rope 33 can be loosened.

[0037] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but they will all fall within the scope of protection of the present invention.
